Average game length - options for change

[Prog]

I did not mean to straight up nerf Storm, but rather to make it a little less "counterish" (if thats a word). Like change the spells in a way to have a little less air bonus damage, but buff the basic damage a bit (like: change Q to 200/300/400/500/600 with + 25% against air). And maybe change or remove the Air-Cannon? The idea is that it should be worse against air (but still a soft counter), while being better against ground to before, so that it becomes a more general pick instead of a straight up counterpick.

And I agree that it probably is a good idea to make it more expansive than Air Ship.
